, p. 700 - 707 (2002)
Isomeric pairs of novel benzofuranonaphthoquinol-type fluorophores (2a-2c and 3a-3c) have been synthesized and their absorption and fluorescence characteristics in solution and in the crystalline state have been studied. Big differences in the absorption

New heterocyclic quinone dyes, 3-(dialkylamino)benzonaphthofuran-6,11-diones, were conveniently prepared from 1,4-naphthoquinone and m-(dialkylamino)phenols.These dyes show dichroic properties and good solubility in a nematic liquid crystalline system.
